Swing type flow divider valve for sluiceway

Abstract

The invention discloses a swing type flow divider valve for a sluiceway. The swing type flow divider valve comprises a groove body, a valve body and a transmission device. The groove body is of a three-way structure, a main groove of the three-way groove body is in butt joint with a main sluiceway body and fixed in a welding mode, a branch groove of the three-way groove body is in butt joint with a branch sluiceway body and fixed in a welding mode, the lower portion of a valve frame of the valve body is connected with a main groove and branch groove included angle connecting plate of the groove body through a bolt, a valve plate connected with a main shaft of the valve body is arranged in the groove body, the transmission device is connected with the upper portion of the valve frame of the valve body through a bolt, the upper end of the main shaft of the valve body is in transmission connection with the transmission device, the transmission device drives the main shaft of the valve body to rotate to drive the valve plate of the valve body to swing, and thus closure transformation of the flow divider valve is achieved. Compared with the prior art, the swing type flow divider valve has the advantages that due to the adoption of the swing type flow divider valve, the sealing performance between the valve plate and the sluiceway is improved, the labor intensity of workers is relieved, the equipment maintenance amount is reduced, and near half investment can be reduced in a project compared with a wedge disc used in the past.

Description

technical field [0001] The invention relates to a valve device for a slag flushing system produced by a blast furnace, in particular to a valve device which is installed at the bifurcation of a slag flushing ditch and a branch ditch, and uses a swing valve plate to divert water slag. Background technique [0002] The ram is one of the important equipment commonly used on the slag ditch of the blast furnace. At present, the ram action mode used by various production plants is the lifting type, and the ram runs along the slideway embedded in the slag ditch wall. Its disadvantages: first, there is water slag residue in the slideway, which leads to poor operation of the ram and poor sealing effect; second, the switching action between the main slag ditch and the branch slag ditch needs to be completed in two steps, which brings inconvenience to the operation; The third is that both the main slag ditch and the branch slag ditch are equipped with flashboards, and the project inves...

AI Technical Summary

Problems solved by technology

It can effectively solve the problem of poor sealing between the gate plate and the slag ditch, improve the labor intensity of workers, reduce the amount of equipment maintenance, and reduce infrastructure investment and production and operation costs
